Which cloud model provides virtualized resources like computing power and storage over the internet?

• A. PaaS
• B. IaaS
• C. SaaS
• D. Cloud Concepts

Answer: (B)

This question tests understanding of cloud service models and what each provides. It asks for the model that delivers virtualized resources like computing power and storage over the internet. The best fit is Infrastructure as a Service, which supplies the fundamental IT resources—virtual machines, storage, and networking—delivered over the internet. You manage the operating system, middleware, and applications on top of these resources, while the provider takes care of the physical hardware, virtualization, and basic network infrastructure. Platform as a Service gives you a ready-made platform for deploying apps (runtime, middleware) rather than raw resources. Software as a Service delivers completed applications accessed over the web. “Cloud Concepts” isn’t a specific service model.
